STATE
106 Incompat MCB-PB 2 Drive rating information stored on the
power board is incompatible with the Main
Control board.
Load compatible version files into drive. 206
107 Replaced MCB-PB 2 Main Control board was replaced and
parameters were not programmed.
a. Press reset.
b. Reprogram parameters.
206
120 I/O Board Mismatch
4
Incorrect I/O board identified. Restore I/O board to original configuration, or,
if new configuration is desired, reset fault.
206
121 I/O Board Comm
Loss 2
Loss of communication to I/O board. Cycle power. 206
122 I/O Board Fail Board failure. a. Cycle power.
b. If fault repeats, replace I/O board.

200 Inverter Dsat
U, V, W
High current was detected in an IGBT. a. Check for loose connection in IGBT wire
harness.
b. Check IGBTs.
c. Check precharge resistors and fuses.
d. Check precharge contactor.

203 Inverter
OverCurrent
U, V, W
High current was detected in an IGBT. a. Verify proper motor data is entered.
b. Reduce current limit.

206 Inverter Unused Bit 4 Inverter section of power structure hard-
ware reported unexpected fault.
Check wiring harness. 206
207 Invtr Gate Kill Inverter gate kill contact is open. Close gate kill contact. 207, 235
208 Rectifier Dsat
R, S, T
High current was detected in an IGBT. a. Check for loose connection in IGBT wire
harness.
b. Check IGBTs.
200
209
210
211 Rectifier IOC
R, S, T
Rectifier overcurrent. a. Verify proper motor data is entered.
b. Reduce current limit.
241

213
214 Reactor Temp Temperature switch in reactor opened. Check for proper temperature and fan
operation.
206
215 Rectifier HW Unused
4
Rectifier section of power structure hard-
ware reported unexpected fault.
Check wiring harness. 206
216 Rectifier Ground
Fault
Excessive ground current measured. Check for grounded input wiring. 220
217 Rectifier Base Temp Excessive rectifier temperatured
measured.
Check for proper temperature and flow rate of
coolant.
218
218
Rectifier IGBT Temp Excessive calculated IGBT temperature. Check for proper temperature and flow rate of
coolant.
218
219 Rectifier IT
Overload
Short-term current rating of rectifier
exceeded.
Low input voltage can result in increased cur-
rent load. Provide proper input voltage to the
drive.
212
220 Rectifier I2T
Overload
Long-term current rating of rectifier
exceeded.
Low input voltage can result in increased cur-
rent load. Provide proper input voltage to the
drive.
212
221 Ride Thru Abort Input power loss timed out. a. Verify input power and connections.
b. Check Line Sync board.
c. Check AC Line I/O board.
210
222 High AC Line Input line voltage is too high. Reduce input voltage to meet specification of
480 ±10%.
211
223 Low DC Bus The bus voltage is too low. Verify proper input voltage. 215
224 Rctfr Over Volt The bus voltage is too high. Monitor the AC line for high line voltage or
transient conditions. Bus overvoltage can also
be caused by motor regeneration. Extend the
decel time or install dynamic brake option.
